--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrea Pinski <[email protected]>: https://gcc.gnu.org/g:95c85b404da4fe6eea7b7f3b51e1270b77f0dab8 commit r17-3902-g95c85b404da4fe6eea7b7f3b51e1270b77f0dab8 Author: Andrea Pinski <[email protected]> Date: Tue Sep 1 23:07:29 2026 -0700 eh: Use tree_could_throw_1/lhs_could_trap_p for lhs in non-call exception case [PR127183] Since `this` argument was added as a non-trapping, we incorrectly had thought it would not cause an non-call exception when it was on the LHS. With the fix for PR127133, we can change the places which were checking for trapping on the lhs to use lhs_could_trap_p/tree_could_throw_1 instead of using tree_could_throw_p. That fixes the non-call exceptions on the lhs of assignments with respect to this argument. Bootstrapped and tested on x86_64-linux-gnu. PR tree-optimization/127183 gcc/ChangeLog: * tree-eh.cc (lower_eh_constructs_2): Use lhs_could_trap_p for lhs. (stmt_could_throw_1_p): Use tree_could_throw_1 for lhs. (tree_could_throw_p): Likewise. gcc/testsuite/ChangeLog: * g++.dg/eh/noncall-this-method-1.C: New test. Signed-off-by: Andrea Pinski <[email protected]>
